Data Compare for SQL Server provides an option of comparing data between backup files or between databases and backup files. This feature can be useful if you want, for example, to retrieve data from a backup file and compare it with your database without restoring or copying the backup from a remote network.
Comparing and synchronizing backup files
With Data Compare for SQL Server you can:
compare a backup file with another backup file or with a database
create a synchronization script from a backup
If you set backup file as a target, the synchronization wizard creates a script to update the database
from which the backup was created. Backup files cannot be modified directly.
If you set backup file as the source, and a database is the target, the database can be synchronized
with the backup.
Compatibility with backup files
Data Compare for SQL Server supports:
native SQL Server backups
If you want to set up a comparison with the backup files usage you should keep in mind that Data
Compare for SQL Server does not support:
tables that do not have a primary key, unique index, or unique constraint
computed columns, but you can compare persisted computed columns
string representations of CLR types (only binary representation is supported)
custom comparison keys, but you can select an alternative unique index, or unique constraint
